Computerworld's Brian Nadel went to Baltimore to try it out, and he reports that Xohm delivered data smoothly to a car moving at highway speeds, played YouTube videos flawlessly, and on average, pushed through more than 3Mbit/sec., compared with 1.3 Mbit/sec. for the AT&T network Brian used as a comparison. But right now, coverage is only planned in a few U.S. cities; if Sprint isn't able to ramp up its coverage quickly, it may lose its advantage.
